Further, the front substrate 111 may have a color filter, and the back substrate 112 may have a thin film transistor (TFT). The TFT includes a black material.

The length BSL of the back substrate 112 can be longer than the length FSL of the front substrate 111, so that TFT lines are connected to the outside of the display panel 110. Namely, an electrode line EL electrically connected to the TFT included in the back substrate 112 can be exposed to the outside due to a difference between the lengths of the front substrate 111 and the back substrate 112. The front substrate 111 can also include a cover layer BM corresponding to the TFT line. For example, the cover layer BM can be black.

Hence, the spacer SP can improve structural stability of the display panel 110.

The back substrate 112 includes a plurality of TFTs in a matrix form. The TFTs can be formed on a portion or the entire surface of the back substrate 112. The electrode line EL is electrically connected to the TFT and can be exposed to the outside of the display panel 110 due to a difference between the lengths of the front substrate 111 and the back substrate 112.

Further, the front substrate 111 includes the cover layer BM positioned opposite the TFT. Further, the cover layer BM can overlap the TFT. Namely, the cover layer BM can cover the TFT when viewed from a front surface of the display panel 110. For example, the cover layer BM can be black.

The display panel 110 includes an active area AA and an inactive area DA. The active area AA is an area, on which an image is displayed, and the inactive area DA is an area, on which the image is not displayed.

For example, the member layer 117 can be a chip-on-film (COF), a chip-on-glass (COG), a flexible printed circuit board (FPCB), a tape carrier package (TCP), and the like. Namely, the electrode line EL can be electrically connected to the TFT, the electrode 115 can be electrically connected to the electrode line EL, and the member layer 117 can be bonded to the electrode 115 and electrically connected to the electrode 115.

The member layer 117 can also be extended to an outer area OA because the length of the back substrate 112 is longer than the length of the front substrate 111. Namely, a configuration or a length of the display panel 110 can include a sum of a length of the active area AA, a length of the inactive area DA, and a length of the electrode 115 or the member layer 117 positioned in the outer area OA.

Next, FIGS. 8 to 10 illustrate another example of a display panel according to an example embodiment of the invention.

The first substrate 111 can be a front substrate, and the second substrate 112 can be a back substrate.

A length FSL of the front substrate 111 can be longer than a length BSL of the back substrate 112, and the length BSL of the back substrate 112 can be shorter than the length FSL of the front substrate 111. Namely, the length FSL of the front substrate 111 can be different from the length BSL of the back substrate 112. The front substrate 111 can also have a TFT, and the back substrate 112 can have a color filter.

Further, the length FSL of the front substrate 111 can be longer than the length BSL of the back substrate 112, so that an electrical line of the TFT is connected to the outside of the display panel 110. Namely, an electrode line EL electrically connected to the TFT included in the front substrate 111 can be exposed to the outside due to a difference between the lengths of the front substrate 111 and the back substrate 112. The front substrate 111 includes a cover layer BM corresponding to the TFT line. For example, the cover layer BM can be black. Hence, the cover layer BM can prevent the TFT line from being reflected on the outside of the display panel 110.

Referring to FIG. 9 which is an enlarged view of a portion SD2 of FIG. 8, a liquid crystal layer LC is formed between the front substrate 111 and the back substrate 112. Further, a spacer SP is positioned between the front substrate 111 and the back substrate 112. The spacer SP can also uniformly maintain a distance between the front substrate 111 and the back substrate 112. Namely, the spacer SP can uniformly maintain a thickness of the liquid crystal layer LC filled in the display panel 110. Hence, the spacer SP improves the structural stability of the display panel 110.

In addition, the front substrate 111 includes a plurality of TFTs formed on the front substrate 111. The TFTs can be arranged on the front substrate 111 in a matrix form and can be formed on a portion or the entire surface of the front substrate 111. The electrode line EL is electrically connected to the TFT and can be exposed to the outside of the display panel 110 due to a difference between the lengths of the front substrate 111 and the back substrate 112.

Further, the front substrate 111 includes switching elements corresponding to the TFTs. The switching element switch on or off a pixel electrode. For example, the pixel electrode can change an arrangement of molecules of the liquid crystal layer LC in response to a control signal received from the outside. The liquid crystal layer LC includes a plurality of liquid crystal molecules, and the arrangement of the liquid crystal molecules change depending on a voltage difference between the pixel electrode and a common electrode. The liquid crystal layer LC also transfers light provided by the backlight unit 120 to the front substrate 111.

In addition, the front substrate 111 includes the cover layer BM in which the cover layer BM is positioned between the TFT and the front substrate 111. The cover layer BM can also contact the TFT. The cover layer BM can be formed on a back surface of the front substrate 111, and the TFT can be formed on the cover layer BM. Further, the cover layer BM can overlap the TFT. Namely, the cover layer BM can cover the TFT when viewed from a front surface of the display panel 110. For example, the cover layer BM can be black.

As discussed above, the display panel 110 includes an active area AA and an inactive area DA. The active area AA is an area, on which an image is displayed, and the inactive area DA is an area, on which the image is not displayed. An electrode 115 can be electrically connected to the electrode line EL and is positioned in the inactive area DA. The electrode 115 can be bonded to the electrode line EL, which is exposed to the outside of the display panel 110 due to a difference between the lengths of the front substrate 111 and the back substrate 112, and can be electrically connected to the TFT. Further, the electrode 115 can be a pad electrode.

Namely, the electrode 115 can be electrically connected to the electrode line EL, and the member layer 117 can be bonded to the electrode 115 and electrically connected to the electrode 115. The member layer 117 bends toward the rear of the back substrate 112 and can be extended toward the main board 321, the timing controller board 319, or the power supply board 315, which are positioned in the rear of the back substrate 112. In addition, the member layer 117 can be extended on the inactive area DA because the length of the front substrate 111 is longer than the length of the back substrate 112. Namely, a configuration or a length of the display panel 110 includes a sum of a length of the active area AA and a length of the inactive area DA. Also, the electrode 115 and the member layer 117 can be connected to each other within a range less than the length of the display panel 110 described with reference to FIGS. 5 to 7. This leads to a reduction in a bezel.

The member layer 117 can also be connected to one side surface, one side, or one edge of the display panel 110, so that a source PCB is connected to the TFT line. The connection between the member layer 117 and the display panel 110 may require the bezel to be formed on one side of the display panel 110. The configuration of the display panel 110 described with reference to FIGS. 8 to 10 is such that the source PCB is connected to the TFT line, and the bezel formed by the connection is removed or minimized its size.

Referring to FIG. 10B, a panel cover 114 covers the side of the display panel 110 and can be referred to as a sealing member.

As shown, a plurality of grooves 144 can be sequentially formed on one side of the side frame 140 and to be separated from one another by a predetermined distance. Each groove 144 extends to the inside of the side frame 140.

The side frame 140 bends at a formation location of the groove 144. The side frame 140 can be formed in a

-shape or

-shape through the bending. The side frame 140 may entirely have

-shape. In addition, a groove 146 can be formed at one end or both ends of the side frame 140. The groove 146 can be formed on a front surface of the side frame 140. Further, the side frame 140 can be formed through the bending, or can be formed by coupling separate frames.

The outer frame 141 forms an outer perimeter of the side frame 140 and can form the first long side LS1, the first short side SS1, and the second short side SS2 of the display device 100. The outer frame 141 can also be formed as one body, or can be formed by coupling separate frames.

The inner frame 143 is connected to the outer frame 141 and extends from the outer frame 141. The inner frame 143 can be a plurality of inner frames. The inner frame 143 can be formed as one body along with the outer frame 141, or can be formed separately from the outer frame 141 and then can be coupled with the outer frame 141. As shown, the inner frame 143 includes a first inner frame 143 LSI, a second inner frame 143 SS1, and a third inner frame 143 SS2. The inner frame 143 and the outer frame 141 may have different heights. A height difference between the inner frame 143 and the outer frame 141 forms (or makes) a step or a stepped portion. The height difference may decrease as it goes from the outer frame 141 to the inner frame 143.

The first inner frame 143 LS1 extends from an outer frame 141 LS1 of the first long side LS1 to the inside of the side frame 140. In this instance, the first inner frame 143 LS1 can be a flat extended plate. The second inner frame 143 SS1 extends from an outer frame 141 SS1 of the first short side SS1 to the inside of the side frame 140.

The reinforcement member 145 is positioned between the outer frame 141, the second inner frame 143 SS1 of the first short side SS1, and the first inner frame 143 LS1 of the first long side LS1. The reinforcement member 145 can also contact the outer frame 141, the second inner frame 143 SS1, or the first inner frame 143 LS1. The reinforcement member 145 also provides rigidity for the side frame 140, so that the bending of the side frame 140 is maintained. The configuration of the reinforcement member 145 adjacent to the first corner C1 can be equally applied to a reinforcement member 145 positioned adjacent to the second corner C2.

In addition, as shown, the inner frame 143 includes a plurality of grooves 140 h. For example, the inner frame 143 LS1 of the first long side LS1 can have five grooves 140 h sequentially formed on the inner frame 143 LS1 of the first long side LS1. The five grooves 140 h are positioned at regular intervals or at irregular intervals. In another embodiment, the inner frame 143 SS1 or 143 SS2 of the first or second short side can have three grooves 140 h sequentially Ruined on the inner frame 143 SS1 of the first short side SS1 at regular intervals.

Next, FIGS. 15 to 29 illustrate examples of assembling components of a display device according to an example embodiment of the invention. Referring to FIG. 15, an optical sheet 125 is positioned on the inside of the side frame 140 and coupled with the side frame 140. The optical sheet 125 can be coupled with the inside of the side frame 140 and inserted into the grooves 140 h included in the side frame 140.

Further, the optical sheet 125 causes light emitted by the light sources to be uniformly transferred to the display panel 110. The optical sheet 125 may also include a plurality of layers such as at least one prism sheet and/or at least one diffusion sheet. The optical sheet 125 also includes at least one coupling portion 125 d to be coupled with the grooves 140 h of the side frame 140. The coupling portion 125 d can also be formed on a first long side, a first short side, and/or a second short side of the optical sheet 125.

Further, the optical sheet 125 may include a plurality of sheets having different functions such as first to third optical sheets. The first optical sheet can function as a diffusion sheet, and the second and third optical sheets can function as a prism sheet. A number and/or a position of the diffusion sheets and the prism sheets can be changed. For example, the optical sheet 125 includes the first optical sheet as the diffusion sheet and the second optical sheet as the prism sheet.

The diffusion sheet prevents light coming from a diffusion plate from being partially concentrated and further uniformizes a diffusion of the light. In addition, the prism sheet concentrates light coming from the diffusion sheet and makes the concentrated light to be vertically incident on the display panel 110.

The coupling portion 125 d can be formed on at least one of edges of the optical sheet 125. The coupling portion 125 d can be formed on at least one of the first to third optical sheets. Further, the coupling portion 125 d can be formed at an edge of the long side of the optical sheet 125. The coupling portions 125 d formed on the first long side of the optical sheet 125 can be arranged irregularly. For example, a number and/or a position of the coupling portions 125 d of the first long side can be different from a number and/or a position of the coupling portions 125 d of the first or second short side.

At least one light assembly 124 can be mounted on a substrate 122 having an electrode pattern for connecting an adaptor to the light assembly 124. For example, a carbon nanotube electrode pattern for connecting the adaptor to the light assembly 124 can be formed on the substrate 122. The substrate 122 can be formed of at least one of polyethylene terephthalate (PET), glass, polycarbonate (PC), and silicon. The substrate 122 can be a printed circuit board (PCB), on which at least one light assembly 124 is mounted.

The light assembly 124 can be a light emitting diode (LED) chip or a LED package including having at least one LED chip. The light assembly 124 can also be configured as a colored LED emitting at least one of red, green, and blue light or a white LED.

A light source included in the light assembly 124 can be a COB (Chip-On-Board) type. The COB light source can be configured such that the LED chip as the light source is directly coupled with the substrate 122. Thus, a process can be simplified. Further, a resistance can be reduced, and a loss of energy resulting from heat can be reduced. Namely, the power efficiency of the light assembly 124 can increase. The COB light source can provide brighter lighting and can be implemented to be thinner and lighter than a related art light source.

Further, an optical layer 123 uniformly provides light provided by the light assembly 124 for the back surface of the display panel 110. Namely, the optical layer 123 can diffuse light provided by the light assembly 124. For example, the optical layer 123 can be a light guide plate. Light, which is provided for the optical layer 123 by the light assembly 124, can be totally reflected from the inside of the optical layer 123 and can be entirely dispersed on the optical layer 123. The optical layer 123 is positioned in the rear of the optical sheet 125. In addition, the substrate 122 and/or the light assembly 124 is positioned on one side of the optical layer 123.

Further, a length of the supporter 142 a can be substantially the same as or slightly different from a length of the coupling portion 125 d of the optical sheet 125. Namely, a posture of the coupling portion 125 d of the optical sheet 125 can be kept by the supporter 142 a.

The pipe 142 b is positioned on the supporter 142 a and extends in an extension direction of the supporter 142 a. A thickness of the pipe 142 b can be greater than a thickness of the supporter 142 a. Namely, the thickness of the pipe 142 b can be greater than a width of the coupling portion 125 d of the optical sheet 125. In other words, the pipe 142 b prevents the coupling portion 125 d of the optical sheet 125 from being detached from the supporter 142 a when the coupling portion 125 d of the optical sheet 125 is inserted into the supporter 142 a. The protrusion 142 c can also be positioned at both ends of the pipe 142 b. After the coupling portion 125 d of the optical sheet 125 is inserted into the supporter 142 a, the protrusion 142 c prevents more efficiently the optical sheet 125 from being detached from the supporter 142 a
